Grade: 8-b Lesson: S3-L9

Explanation: Hello Students, time to practice and review the steps. Let us take next 2-5 minutes to solve the steps for the problems. This is a good exercise to check your understanding of the concepts.Second student to identify and review important steps.Focus on understanding the concepts and application to solving problems step by step.

Lesson Steps

Steps	Problem	Solution
1	Find the indicated real \$n^(th)\$ root	\$ n = 2, a = -16 \$
2	Given surd	\$ root(n)(a) = root(2)(-16) \$
3	Now 16 can be written as exponential form	\$ root(2)((4i)^2) \$
4	Cancelled 2th root and power 2	\$ ((4i)^2)^(1/2) \$
5	Hence their is no real root for given surd	\$ 4i \$
6	Answer	\$ B = 4i \$

Steps

Problem

Solution

Find the indicated real \$n^(th)\$ root

\$ n = 2, a = -16 \$

Given surd

\$ root(n)(a) = root(2)(-16) \$

Now 16 can be written as exponential form

\$ root(2)((4i)^2) \$

Cancelled 2th root and power 2

\$ ((4i)^2)^(1/2) \$

Hence their is no real root for given surd

\$ 4i \$

Answer

\$ B = 4i \$
